The requirement comes from Ozone. In Ozone, if one of the OM Ratis server is 
lagging behind and needs to install a snapshot to catch up, it would have to 
stop it's Ratis server so that there are no transactions applied in the 
meanwhile. If Ratis provides an option to pause/ unpause its state, OM Ratis 
server would not have to be stopped in this process.

[~hanishakoneru] thanks!

Can you share a bit context on this JIRA? Is there some papers/systems doing 
this? Or is there a requirement from hadoop-ozone to ask ratis supports this?
